Artist's concept of planet Kepler-69c, a super-Earth-size planet (70% larger than Earth). It is the smallest yet found orbiting in the habitable zone of a sun-like star. Its orbit of 242 days resembles that of our neighboring planet Venus.

Description

Kepler-69 is a two planet system which was discovered by Kepler. Kepler-69 b is a planet in a 14 day orbit and too hot to sustain liquid water on the surface. However, the outer planet, Kepler-69 c, might be in the habitable zone.edit

Kepler-69 is a two planet system discovered by Kepler. Kepler-69 c, the outer planet, is orbiting the star every 242 days and might be in the habitable zone. It is 70 percent larger than Earth. Not much is known about its composition.edit

Planet sizes

The following plot shows the approximate sizes of the planets in this system
The Solar System planets are shown as a comparison.
Note that unless the radius has been determined through a transit observation, this is only an approximation (see Lissauer et al. 2011b).

Habitable zone

The following plot shows the approximate location of the planets in this system with respect to the habitable zone (green) and the size of the star (red).
This is only an estimate, using the star's spectral type and mass.
Note that if no green band is shown in the plot, then the planet's orbit is far outside the habitable zone.
The equations of Selsis, Kasting et al are used to draw the inner and outer boundaries.
